Granite muaj li ntawm volcanic lava nyob rau hauv lub siab heev siab nyob rau hauv lub qhov dej ntawm lub cev ntawm lub ntiaj teb ua kiav txhab, magma yuav nto tawm hauv av, thiab hauv av maj mam txias solidification tom qab tsim ntawm tectonite, yog ib yam tob tob hauv acidic pob zeb, muaj pob zeb magmatic (volcanic pob zeb). Granite yog lub ntsiab tivthaiv ntawm quartz, feldspar thiab mica. Cov ntsiab lus ntawm feldspar yog 40% -60%, quartz cov ntsiab lus yog 20% -40%, nws cov xim nyob ntawm seb hom thiab ntau npaum li cas ntawm cov composition. Lub pob zeb yog tawv thiab ntom.
Lub cev lub cev
Granite yog ib yam khoom tshwj xeeb, tus cwj pwm ntawm lub ntsiab ntawm lub ntsiab yog li Porosity / permeability: granite lub cev permeability yuav luag negligible, ntawm 0.2% thiab 4% thermal stability: qhov kub ntawm lub granite muaj zog, nws yuav tsis hloov vim hais tias ntawm kev hloov ntawm ambient kub, granite vim nws high ntom thiab yuav tsis hloov vim qhov hloov ntawm qhov kub thiab txias sau.
Granite muaj lub zog ua kom muaj zog, yog li nws tau siv rau hauv cov khoom ntawm cov khoom siv tshuaj tua hluav taws hauv cov khoom siv: granite range extension coefficient ntawm 4.7 x 10-6-9.0 x10-6 inch nto (x). Xim: cov xim ntawm cov granite thiab cov hardness ntawm cov ntaub ntawv yog heev raws li: granite yog cov ntaub ntawv tshaj plaws, kuj vim nws cov superior hardness thiab ua rau nws muaj zoo coj kuj.
Muaj pes tsawg leeg: granite yog tsim los ntawm quartz thiab orthofeldspar thiab microcline. Qhov feem ntau txheej txheem granite yog tsim los ntawm cov nram qab no peb qhov: feldspar quartz dub mica. Feem ntau ntawm cov khoom feem ntau yog txiav txim siab los ntawm cov xim thiab cov khoom, tab sis feem ntau feem ntau ntawm cov khoom feldspar yog 65% -90% quartz 10% -60% black mica 10% -15%
yam ntxwv
Granite zoo nkauj, ruaj thiab nyuab heev. Nyob rau lub sij hawm qub, yog tias muaj cov zoo meej mining, cov khoom siv thiab kev siv tshuab, nws yuav tsum muaj ntau nrov dua marble.
Granite feem ntau muaj lwm yam minerals, xws li amphibolite thiab mica, thiab nthuav qhia ntau yam xim, xws li: xim av, ntsuab, liab thiab dub. Vim hais tias nws crystallizes qeeb, nws muaju yog intertwined, zoo li lub thawv rubic,
Yog li ntawd nws nyuaj. Nws zoo li ua lub tsev, tsis txhob poob qis dua, tsis khawb, thiab tsis txhob sov siab. Tsis hais xim los yog lub teeb, yog tias muaj qee qhov kev nkag siab ntawm kev txuag, nws yuav tsis ploj los yog ploj. Nws yog dawb ntawm kev ua qias tuaj, nrog siab gloss nyob rau saum npoo ntawm qhov txhuam ntawm qhov kawg, thiab cov huab cua ntawm txhua yam huab cua uas yuav tsis yog ua kom tiav.
Cov mining ntawm granite feem ntau yog ua ntawm xaim hlua sawing. Muaj cov tswv yim tshiab xws li kev sib txheeb thiab qhov nplaim dav hlau. Lub pob zeb txiav los ntawm nplaim taws tsuag yog txoj kev zoo thiab zoo, thiab kev ua tau zoo tshaj plaws yog siab. Lub pob zeb uas tau sau los ua hu ua cov khoom siv khib nyiab tom qab coarse, thiab tom qab ntawd ua los ntawm cov pob zeb drilling los yog tshuab saws, qhov yuav tsum tau loj me me ntawm daim thiab daim hlau. Txhawm rau ntawm lub cylindrical los yog arcuate nrog lub tshuab milling lossis lub txaj swb; Thaum kawg, nws yog siv los txiav tuab, raug nplua zoo, los yog grind, txhuam thiab txhuam qhov npoo. Granite tsis pollute qhov chaw. Cov khoom siv hluavtaws yog feem ntau txuam nrog kev phem, kev lom neeg, cov khoom siv thiab xav tau hloov ntau zaus hauv kev tsim kho (txhua zaus muaj teeb meem). Granite tsis tas yuav tau hloov vim nws yog qhov ntev heev.
Tsis tas li ntawd, granite yog heev cov tswv yim thiab ua tau rau hauv ntau qhov chaw - polishing, sublight, nplua nplua, hluav taws, dej riam kho thiab sandblasting. Vim hais tias cov granite feem ntau muaj cov khoom siv hluav taws xob, nws yog ib qho tsim nyog los ntsuas nws cov hluav taws xob theem thaum siv cov granite thiab tom qab kom paub meej tias nws siv.
Tus xaiv thiab yuav
1. Kos cov khoom siv rau cov khoom siv pob zeb, thiab lawv cov khoom siv puas zoo los yog zoo tshaj natural granite (JB / T 7974-2001).
2. Yuav tsum muaj kev soj ntsuam zoo: qhov loj ntawm cov duab los yog kev sib txawv ntawm kev sib txawv tsis yog ntau tshaj 1 hli, dav, thickness, ntxiv los yog rho 1mm, qhov chaw seem thaj chaw los yog tus nqi sib txawv yog tsawg dua 0.5 hli, kab kev cai ntawm kab pheeb ces kaum los yog sib txawv tus nqi yog tsawg dua 0.5 hli.
3. Txawm tias qhov zoo ntawm lub granite platform yog sab saum toj, xim, xim txawv thiab qauv ntawm qhov thaiv yuav tsum tau sib raug zoo thiab tsis tsim nyog.
4. Seb tus npla ntawm lub platform muaj ploj ntug, tsis muaj lub qe, nrib pleb, xim nqaij tawv, xim kab, qhov zoo li qhov ntxeev.
5. Seb tus nplais ntawm lub platform yog pleev xim rau nrog rau lub pob zeb tiv thaiv lub pob zeb kom paub tseeb tias cov dej tsis zoo thiab cov khoom foob pob zeb ntawm cov khoom siv pob zeb.
6. Seb lub lub pob zeb yog xyuas los ntawm lub teb chaws pob zeb zoo saib xyuas, nrog rau lub cev, xov tooj cua, khov-thaw, thiab cov ntaub ntawv soj ntsuam.
7. Keeb kwm thiab lub npe pob zeb pob zeb.
